Mainboards with errors in image export control areas can also cause the screen to be white. This is a serious hardware flaw and often requires a professional technician to handle it.

Some viruses can interfere with the display system, making it impossible to display the desktop screen after startup, causing a white screen.

Do not remove the device yourself if you are not experienced because it can damage other components.
It is recommended to bring a reputable repair center if the cause cannot be determined.
